Phoronix: FSF Talks Up Libreboot As New Coreboot Downstream
Libreboot is a de-blobbed version of Coreboot designed to run on the Free Software Foundation's first endorsed laptop...
Better names, yes. Open Source projects frequently suffer from having really bad names.The Gluglug X60 has also been renamed to the Libreboot X60.
You need to be absolutly sure with regards to security? Need to be able to audit or change every line of code running? Or are just a purist that just wants to be able to do it for political or moral reasons? Pick this, a deblobed kernel and one of those distros the FSF recommends.
If you don't? Well, don't use it. Pick coreboot or use the UEFI bloat that ships with your mashine and be happy. But you do have the choice.
Anyway there are still software bugs that can be used to exploit OS, so I doubt if any government or corporation would spend money on backdoors. It's cheaper to have large collection of exploits.
